Max Maths, Year 4, Practice, Timetables and schedules

In the Max Maths Year 4 practice material, students learn to calculate time durations and understand timetables and schedules through the example of Padma's exam day. In one scenario, Padma has an English exam starting at 9.00 a.m., lasting for 1 hour and 30 minutes. By breaking down the duration into smaller increments and plotting them on a timeline, it's demonstrated that the exam will finish at 10.45 a.m. This visual representation with a timeline helps students grasp the concept of adding time intervals to determine an end time.

Another example involves Padma preparing for her Maths exam by reading her study notes for 1 hour and 15 minutes. To find out when she should start reading, the timeline is used in reverse. Knowing her exam begins at 11.45 a.m., students learn to work backwards from this time, subtracting the duration of her study period. The timeline shows that Padma should begin reading at 10.30 a.m. The practice section provides further exercises where students apply these principles, such as determining the end time of a 45-minute Music exam and figuring out when Padma should start reading her notes if she needs 45 minutes of preparation before the Music exam.
